TO ALL WHOM IT MAY CONCERN:

Beit known that I, WILLIAM MOLLER, of New York, in the county and State of New York, have invented a. newrand improved Arrangement for Cooling Animal Coal; and I do hereby declare that the following is a, full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings, and to the letters of reference marked thereon.

Figure 1 represents a cross-section; and

Figure .2, a top view of my improved arrangement,

Animal coal, afterbcing reburned, requires to be perfectly cooled before the some can be used in the filters. For that purpose, the coal is spread out usually in thin layers upon the floor, and is there occasionally shuflled over until cooled ofi'. By this operation, much coal dust is made, which is consequently a great loss. To obviate this handling and shuttling of the coal, and to prevent as much as possible the making of coal dust, forms the nature of my invention. p i

For thispurpose I arrange on the floor A diagonal plates, B B, which may be fastened perfectly tight to the floor A, as well as to the sides of the building C C. To the inside of those plates B, I attach plates D, so as to form, together with the upper parts of the plates B, small chambers. The bottoms of those plates D are cut out so as to form large openings, m, to allow the coal to fall out easily from the upper chambers E into the lower chambers F, formed by the lower part of the plates B. The upper edges of the plates D may be arranged so as to form a rail-track for a coalcar to run upon. On the bottom oi the chambers F, below the floor A, pipes G are attached, at suitable distances apart,'to draw off the coal contained in those lower chambers F. The reburned coal is brought from the oven, and emptied into the upper chambers E the same falls then through the openings 12:. into thclower chambers F, and is then takenatvay from those'chambers F when perfectly cooled, through the pipes Gr. By this arrangement ofthe diagonal plates B and D, forming several chambers, the coal is made to pass slowly from one chamber into the other chamber. in thin layers, and is subjected to the cold atmosphere not only, on the surface, but likewise where in contact with the plates B or D, and for which purpose a current'of cold air may be forced into the chambers H, outside of the; plates B, as well as into the upper part of the chambers F to cool the plates B and D.'

What I claim as my invention, and desire to secure by Letters Patent, is-

The arrangement and combination of the diagonal plates B and D, forming chambers for thc'purpose of facilitating the cooling of animal coal, substantially as set forth and described.
